Okay, I've got my docking station together and running. For the serial hack I just built an intermediate cable, that connects to the docking harness on one end, and onto the factory-supplied serial patch cable at the other end. The "home dock detection" hack was added on this intermediate cable, connecting the CD signal to TX-Data.
I think most folks might want to go a similar route, since the serial connector on the docking harness is the "wrong sex" to begin with, so some kind of sex-change adaptor/cable is required there.
And, no, the software hack for "home dock detection" is not available (from me) yet. Real Soon Now.
Cheers
